2020-10-26 · The urine antigen test for detection of Legionnaire’s disease (LD) can remain positive for weeks or months after initial infection. So a positive test in a patient with pneumonia may not just be suggestive of an acute infection but also the diagnosis of LD during recent weeks or months (1,2).

The pneumocococcal urine antigen test (UAT) is an assay commonly used to identify pneumococcal antigens excreted into the urine to increase the rate of specific microbiological diagnosis over conventional culture methods [2, 3]. Positive tests have been associated with more severe disease This test has demonstrated reasonable sensitivity and good specificity in different studies. 8-13 Nevertheless, the clinical usefulness of this pneumococcal urinary antigen test is not well defined, and, consequently, current guidelines do not clearly recommend the situations in which testing should be performed. culture confirmation of pneumococcal disease.

Pneumococcal and legionella urinary antigen tests

Respiratory infections such as avian influenza, pneumonic plague, pneumonic tularemia, SARS, and MERS could present in a way similar to both Legionnaire’s disease and pneumococcal pneumonia, and, in the right patient, a positive or negative test result may be able to provide crucial information that could have cascading impacts. Streptococcus pneumoniae and Legionella pneumophila remain the major etiological agents and are responsible for a significant proportion of CAP mortality. Among diagnostic tests for CAP, urine antigen detection of S. pneumoniae and L. pneumophila is widely accepted due to the simplicity of collection and the rapidity of the test results. In addition to sputum cultures, blood cultures (when indicated), and respiratory viral testing, urinary antigen testing for 2 specific etiologies – the pneumococcus ( Streptococcus pneumoniae) and Legionella pneumophilia serogroup I – are frequently performed. Pneumococcal and Legionella urinary antigen tests are specific and moderately sensitive, but their utilityin low-resource settings is uncertain.

Problemet var spridning av Klebsiella pneumoniae mellan patienterna. Luftkonditioneringsanläggningar kan sprida legionella (113).

The Xpert MTB/RIF (Cepheid, USA) platform and rapid assays for urinary lipoarabinomannan can substantially speed up tuberculosis diagnosis; the current challenge is to translate this intoearlier Urinary antigen testing has grown in popularity for several significant respiratory infections, particularly Legionella pneumophila, Streptococcus pneumoniae, and Histoplasma capsulatum. By capitalizing on the concentration of shed antigen from a variety of pathogens in the kidneys for excretion in the urine, urinary antigen testing can be used to obtain rapid test results related to Legionella serum antibodies are rarely of diagnostic value, but may be useful in epidemiological investigations; Legionnaires' Disease is a notifiable disease.
